SNARE DRUM.

Application led July S, 1921, Serial No. 483,154. Renewed June 25, 1923.

T 0 all 'whom t muy concern.'

Be it known that I, ROBERT C. DANLY, a citizen of the United States ofAmerica, and a resident of Chicago, in the county of Cook, State ofIllinois, have inventedcertain new and useful Improvements in SnareDrums, of which the following is a speci tication.

This invention relates to means for moving the snares of snare drumsinto and outv of their active position, and has for its object:

'IO provide a structural formation and association of parts andmechanisms whereby the adjustable carriers of the snares;y areinterconnected so as to move in unison to attain an even and uniformmovement of the whole lengths of the snares towards and away from thesurface of the drum heador skin, and with which a predeterminedytensioning of the snares is maintained without change during saidmovements, all as will hereinafter more fully appear.

In the accompanying drawing:-

Fig. l, is detail central longitudinal sectional elevation of an end ofa drum, with the preferred form of this invention applied thereto. f

Fig. 2, is a frontelevation of one of coupled snare carrying mechanisms.

Fig. 3, is a similar view with the parts removed.

Fig. 4, is a horizontal section on line 4-4, Fig. l.

Fig. 5, is a detail vertical section on line 5 5. Fig. 2.

Like reference numerals parts in the several' views.

Referring to the drawing, l designates thel usual main cylindrical shellof a drum having at each end a straining hoop 2, with each of saidstraining hoops comprising the usual skin hoop 2', and an externalhoop-2 associated with said skin hoop tov form a raised circular rim beyondthe headV or skin 3. Said external hoop is preferably formed of metalhavethe offset or Z form shown in Fig. l.

4 designates the drum snare of anyA usual indicate like formation, whichin this construction is at#` tached at its respectivelends to carryingmembers 5 and 5 havingy movement 1nplanes at right angles to the head orskin 3 of the drumv in the simultaneous manner hereinafter described toattain a uniform adjustment of the entire snare to and from contact withsaid drum head. In the attainment of the above mentioned simultaneousmovements of the parts, as well as the initial tensioning of the snaremember itself, a counter-part construction and arrangement Of parts atopposite sides of the drum is employed as follows: v

6 designates a base plate, or member secured to an outer face of the4shell 1 and formed with a journal orifice for the hereinafter describedcrank hub and with upper guide ears 7 and lowerA guide iange 8 forguiding the intermediate companion plate or slide now to be described.

9 designates the intermediate plate or slide adapted for guidingengagement in the guide ears 7 and flanges8 aforesaid, to move in aplanev parallel' with the face of the shell l and in a plane at rightangles to the face of the drum head or skin 3. Near its mid-length theyslide 9 is formed with a transverse slot 10 for operative engagementwith the crank pin or block of the Operating hub hereinafter described,and at its lower end the slide 9 is provided with a flange 11 tO afforda bearing for the adjusting screw of a cross head as follows.

l2 designates a cross head having sliding engagement. with the lowerportion of the slide 9 and formed withI a central lug 13' having a screwthreaded orifice for engagement with the screw threaded shank of anadjusting thumb screw 14 which is revolubly mounted in the' aforesaidflange 11 of the slide 9, so that by a manual turning of said screw, thecross' head 12 is adjusted as desired along the slide 9 for the purposehereinafter set forth.

15 designates a revoluble hub formed with an offset in its periphery forbearing engagement intheabovel described bearing Orifice of the; fixedbase plate 6 and'having an axialv boreofj any usual non-circularform-ationV adapted to engage with an end of the connecting shafthereinafterv described so that theY parts will turn in a simultaneousmanner. In the construction axial bore is attained by radial slots 16connec g with il bore and adapted to receive cross pins ot saidconnecting shaft.

designates a crank pin mounted in the outer tace ot the hub l55preferably ot the ectangular form shown and having operativeengageniient With the transverse slot 10 of the slide 9 aforesaid, sothat with a turning movement oi the hub a vertical movement will beimparted to the slide 9. ln such preferred construction ot the crank pinit? the same is provided with a circular shank i8 fitting and turninfina correspending1 oritice in the hub 'l55 and held in place by tieengagement ot the inner portion oi: the hereinafter described rod orhandle in a. circumferential groove in said shanlr 18 as shot/v* moreparticularly in Tdig.

i9 designates the connecting` shaft above referred to, extending` acrossthe interior oi the drum shell l and having` non-circular ends adaptedto engage the like non-circa lar bores oil a pair ot hubs 15 arranged atopposite sides ot the shell l to impose simulw taneous revolution onsaid hubs in a inanual turning' adjustment of either hub.

20 designates an operating` rod or handle extendingradially :trom a hub"l5 for convenient manual turningmovement oi' the hub` and in theconstruction shown the inner portion of the rod presses transverselythrough the hub l5 and is riveted or other- Wise tixedly secured inplace.

llach ot the counterpart snare carrying members 5, 5 aforesaid is formedWith an upper semi-circular or arched portion 21 adapted to overhang anadjacent portion ot a strain hoop 2. and With a depending' shank portion22, the lower end of which is pivotally connected to' the aforesaidcross head l2, preferably by a return bend 22" engaging the rear edge otthe cross head l2 and held in place by contact W'th the ad Iiacent 'faceo1" the associated slide 9,

shown more particularly in llig. 5. The tree and inner end of archedportion 2l 01' a carrying` member is laterally widened and has flangedform as shown adapted to aftord a substantial holding abutment. for onoend ot the snare member 41;. which is clamped in place thereon by aholding` bar 23 and a plurality ot clamping screws shown in Figs. l and24; designates an adjusting thumb screw passing' through the upperportion of the shank portion 22 ot the. carryingn member and havingbearing against the upper end ot' the slide 9, preferably by a reducedend of said scren7 having bearing engagement with a vertical groove onslot 25 in the upper portion oi" the slide 9.

ln the practical use oi the present con struction, the respective endsoie the drum snare l are secured to the respective holdiaeresa ing endsot the carrying members 5, 5 in an even and proper manner, after whichthe proper tensioning` ot the snare is effected by one or the other, orby both of the thumb screws 2d.

lf'he vertical adjustment oi the res )estive ends ot the snare t toattain proper relation to the drinn head or skin is then effected by oneorvthe otl er of the djusting thumb screws lll.

lilith the above described initial adjust ments effected, the snaremechaifsm is ready for actual use. and so that by a pan tial rotation byhand of the connected crank hubs l5 simultaneous movement is imparted tothe snare carrying members 5, 5 in paths at right angles to the lace orthe drum head or skin 3, to bring the snare a into uniform Contact withthe drum head or skin along the entire length oit the snare, or toremove the snare from such contact in a like manner. lil-.lith themovement ot the parts in the manner described, the initial tensioning`ot the snare is preserved during' the different and repeated movementset the same to and from the drum head or slain.
